Hmm…after upgrading the 2.5.1, the plugin kinda caused a fatal error when I tried to activate it. =/ WP then didn’t allow it to be activated. Bummers. I was searching aroung the plugins directory for it when I noticed it doesn’t even show up on the first page even if I put ” around the word “Subscribe” to make it a compulsory keywords.
And nope, there doesn’t seem to be another plugin like it at the moment. =/
